Mac Mini Problem.. QuickTime 7.0 playing HD Trailer. Video very choppy

iMovie workaround
When i realized that the new HD trailers were REALLY choppy on my 1.25 PB, I thought I might as well try editing the HD footage in iMovie HD and see how that works. After importing the BBC motion footage into iMovie using the HDV widescreen format, I could watch the entire thing in all its HD glory. No choppiness whatsoever. It took a few minutes to import it as a clip but it was pretty neat. In the end though, it wasn't anything super cool.

Everybody here is missing the problem.
The problem is playing back H.264 on a low spec. computer. Not paying HD on a low spec computer. Playing HD is no problem is the decoding of H.264 that requires power.

iMovie HD probably down sampled the 1080p to 720p so what you saw wasn't actually as good.
wait, can someone confirm that? it runs ok during "present movie"?
the only way to do that is buy QT7... nice.
i have to admit i was a bit shocked when my 1.6ghz G5 couldn't handle H.264, but then, i don't know much about HD and i don't really need to use it at this point, so it's pure novelty...

there you have it...
I figured as much, but since I don't know jack about HD I wasn't about to venture an uninformed guess about what iMovie may have done to the the footage to make it play smoother. So, on a side note then, can iMovie handle 1080 or would you have to move up and purchase Final Cut Pro HD for 1080 editing capability?

iMovie handles HD (technically HDV) by first converting it to Apple Intermediate Codec, which plays fine on low-end Macs < 1.5 Ghz G4s. Its a long process that requires a lot of disk space. AIC also is not a very good codec visually.nuclearwinter said:
However, with FCP HD, you can edit all types of HD formats, including native HDV. In case you don't know what HDV is, it is long-GOP MPEG2 which requires a lot of processing power to decode, and edit. So with native HDV editing, its recommended you'll need a dual G5. The great thing about editing in native HDV, is there is no transcoding and waste of disk space.
Sad
It's sad when the newest model Powerbook can't handle one of the biggest hypes of the new OS.

You can just pause the movie and wait until it completely downloads, then play it. Simple.

From what I've tried this simply isn't the case- HD content requires A LOT of processing power- the 1280x544 stuff is bad enough on my g4 iMac- forget about even playing the 1920x1080 HD stuff- not a chance even when fully downloaded.
each frame is just over 2 million pixels so that's 49,766,400 pixels per second or 2,985,984,000 per minute. An hours worth of content would require quicktime to redraw 179,159,040,000 pixels- me thinks that's a lot of processing power neede for this task

ROFL!!
Dr. Jones, I make a typo here and there, but that one was quite funny!!
I am glad your issue is resloved, and hopefully we didn't tarnish your love for the macrumors world by seeing humor in that slip!
Best of luck with your Mini and welcome!!
Does HD really matter since the resolutions of the video are higher than than the sceens which most people have. I keep my comp at 1152x864 and i tried it on the emacs at school and i couldnt get the standard size video to even fit on the screen, but once i fit it on the screen it played fine.(1.25 ghz emac)
